Summary

This trial is comparing two different ways to fix a burst brain aneurysm in people not previously included in a study.

Who is the study for?
This trial is for adults over 18 with a documented brain aneurysm that has ruptured in the last month. They should be stable enough to undergo surgery or endovascular treatment, as judged by their medical team. People can't join if they're allergic to contrast material used in scans, have aneurysms linked to arteriovenous malformations (AVMs), or if the aneurysm is at the basilar apex.Check my eligibility
What is being tested?
The study aims to compare two treatments for ruptured brain aneurysms: surgical clipping and endovascular coiling. These are different methods of preventing further bleeding from the weakened blood vessel area in the brain.See study design
What are the potential side effects?
Potential side effects may include complications related to surgery such as infection, reaction to anesthesia, stroke, re-bleeding of the aneurysm and neurological deficits. Endovascular treatment risks could involve damage to blood vessels, bleeding or clotting issues.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
poor clinical outcome(mRS>2)
Secondary outcome measures
Failure of aneurysm occlusion using the intended treatment modality
Occurence of a "major" (saccular) aneurysm recurrence
Occurence of aneurysm re-rupture following randomization but before treatment initiation

Trial Design

2Treatment groups
Active Control
Group I: Surgical managementActive Control1 Intervention
Surgical clipping will be performed as soon as possible following randomization, according to standards of practice, and under general anesthesia. Aneurysms thought by the treating physicians to require deliberate permanent proximal vessel occlusion, construction of a surgical bypass, or other flow-redirecting treatments that do not directly clip the aneurysm will not be excluded; these non-ISAT aneurysms are expected to be more difficult lesions to manage surgically as well as endovascularly.
Group II: Endovascular managementActive Control1 Intervention
Endovascular treatment will be performed as soon as possible following randomization, according to standards of practice, and under general anesthesia. Details regarding type of coils, use of adjunctive techniques such as balloon-remodeling, stents or flow-diverters, as well as post-treatment medical management issues, will be left up to the physician performing the endovascular treatment.
